   Japanese Knotweed in the village    September 2, 2013

Japanese Knotweed must be reported as soon as possible to the local council or the Clerk, to be dealt with professionally.   How Japanese knotweed spreads

 

It spreads through its crown, rhizome (underground stem) and stem segments, rather than its seeds. The weed can grow a metre in a month and can cause havoc below concrete and tarmac, coming up through the resulting cracks and damaging buildings and roads. Studies have shown that a 1cm section of rhizome can produce a new plant in 10 days. Rhizome segments can remain dormant in soil for twenty years before producing new plants.
